Everything Everywhere All at Once

The IDE from the future: think out loud, and your scattered ideas become a plan a team of agents can build.

I built it solo in ten days, in Rust and TypeScript, on Meta’s Muse models.

A native Rust Mac app is coming soon.

It starts at your thinking, not at a file tree

Speak, type or sketch. Muse Voice Transcribe turns speech into words, and Muse Spark puts each idea in its place and asks about what’s unclear right beside your words. Sketch how it fits, and Muse Image draws it back. Your original words stay one step away.

You can follow the agents

Crew, a team of agents on Muse Spark, builds board parts in parallel on real Git branches. Each part is checked; one that fails gets a repair, and what passes merges through dev, staging and main in front of you. Finished parts get reused, so the next build starts ahead.

Anyone who can explain an idea can now direct a team of agents.

The live demo opens a sample project with no sign-in and capped model use. Crew runs locally, because it writes Git repositories on your machine.
